What should happen when you add or multiply inverse numbers?
When you add a number and its additive inverse, for example x+(-x), you would get 0 as an answer no matter what the number is. When you multiply a number and its reciprocal or multiplicative inverse, for example x*(1/x), you would always get 1 as an answer.
What is the additive inverse of the expression a - b?
I believe that the answer to this question is -a+b, as an additive inverse is supposed to make the equation equal to zero when you add the inverse and its equation together. That means that when you add -a and a, you get zero, and -b and b is zero as well, so this would be the most logical explanation to your question.
